Subweb and topic names - conflicts, view URLs, and links
If your TWiki installation has the hierarchical webs feature turned on,
you face subtle issues about subweb (web inside a web) and topic names.
If you are unfamiliar with subwebs, please read ManagingWebs#Hierarchical_Webs
TWiki 5.1.2 has introduced measures to take care of those issues.

In that case, http://twiki.example.com/cgi-bin/view/AaAa/BbBb shows AaAa.BbBb topic while http://twiki.example.com/cgi-bin/view/AaAa/BbBb/ shows the home page of the

You can link to a subweb in a relative manner.
The old behavior was to make a link to create the "missing topic"

And they have to become links - otherwise the label in
If so, there is no other link destination than
